ELECTROLUMINESCENT SCREEN Russian patent published in 1997 - IPC

FIELD: electroluminescent light sources; information display devices. SUBSTANCE: electroluminescent screen has transparent dielectric substrate whose cavity mounts tandem-arranged transparent bottom strip electrodes, first dielectric layer, luminescent layer, and second dielectric layer. Dielectric constant of transparent dielectric substrate is lower than that of first and second dielectric layers. Top strip electrodes are deposited on substrate incorporating structure inside it; these electrodes are crossed at right angle to bottom strip electrodes. Electroluminescent layer is located at points of intersection of bottom and top strip electrodes. Thickness of four first layers of structure equals depth of grooves in dielectric substrate. EFFECT: improved design of screen. 2 dwg
